Thread-local variable wrapper

Implementations

Creates a new empty ThreadLocal.

Creates a new ThreadLocal with an initial capacity. If less than the capacity threads access the thread local it will never reallocate. The capacity may be rounded up to the nearest power of two.

Returns the element for the current thread, if it exists.

Returns the element for the current thread, or creates it if it doesn’t exist.

Returns the element for the current thread, or creates it if it doesn’t exist. If create fails, that error is returned and no element is added.

Returns an iterator over the local values of all threads in unspecified order.

This call can be done safely, as T is required to implement Sync.

Returns a mutable iterator over the local values of all threads in unspecified order.

Since this call borrows the ThreadLocal mutably, this operation can be done safely—the mutable borrow statically guarantees no other threads are currently accessing their associated values.

Removes all thread-specific values from the ThreadLocal, effectively reseting it to its original state.

Since this call borrows the ThreadLocal mutably, this operation can be done safely—the mutable borrow statically guarantees no other threads are currently accessing their associated values.

Returns the element for the current thread, or creates a default one if it doesn’t exist.
